Abstract

Due to criteria for building energy efficiency today`s buildings are better insulated and the envelope is more air tight. These improvements have led to a more comfortable buildings and lower running costs. However, the new indoor environments are more dependent on controlled ventilation system thus, the role of ventilation is emphasised. Impurities in indoor air can originate from different sources: e.g. materials, structures, adjacent zones such as crawl spaces or attics or ventilation systems. Ventilation and pressure differences as well as leakage routes are key factors in understanding the concentrations of impurities in indoor air and their penetration to indoor air. This paper reviews the current understanding of the relationship between ventilation and its effect on sick building syndrome.
